Project: North Delta Flood Control and Ecosystem Restoration Project

Description: The North Delta Flood Control and Ecosystem Restoration Project consists of flood control and habitat improvements where the Mokelumne River, Cosumnes River, Dry Creek, and Morrison Creek converge. Flood flows and high water conditions in this area threaten levees, bridges, and roadways. The project will reduce flooding and provide contiguous aquatic and floodplain habitat along the downstream portion of the Cosumnes River Preserve by modifying levees on McCormack-Williamson Tract and at Grizzly Slough.
